My NEC is 1365x768. I can get 1360x768 1:1 out of MyHD with some of fiddling and it looks alot better than 720P or 1080i using the same DVI connection.

Rich,

I assume you figured out the problem you had with the image being shifted? I saw your troubles on the HTPC forum. I am considerring the same plasma and was a little taken back when I read about your myHD problems as I am going to use myHD also.

If you figured it out what was it?

Have you tried SageTV with the NEC?

I can get the MyHD to work by compensating with the horizontal shift on the NEC. Unfortunately, this ruins my desktop.

I brought this up again in the "Unofficial MyHD support" thread and was not well received by Cliff Watson (who seems to be the self appointed guru). I was instructed to return my card and personally attacked. It was most unpleasant. So I monitor that thread but stay off it.
I can only hope that someone from MIT is paying attention to this forum.
Cliff is apparently tied into DigitalConnections and they are
non-responsive, so far anyway.

While I like the DVI output of the MYHD card. The reliability and software quality is only fair. You have to run the Beta software to avoid crashes with the newer cards due to memory timing problems.

It is really too bad because all they would have to do is implement some advanced image adjustment controls and it would work fine.
People like me would be willing to try experiments if they do not have the hardware necessary to test. That does not seem to be the cards.

While I applaud the efforts of small companies like MIT, I think that sooner or later they will have to realize that customers want to buy products that work not beta's. They are quite understanding if you treat them right.

I would buy the Plasma you want and not worry about $300 HTDV cards. They are only interim solutions. Eventually, we will get a quality card that can supply true PVR functionality.

I have never tried SaveTV since I have a TiVo. I use the MyHD for Hi-Def tuning/recording only.

Rich,

Thanks for the reply. I saw your interchange with Cliff on that thread and was appalled at his responses to you. (I've seem him behave the same way to others) If he is an MIT employee I'ld say that's inexcusable. If he's just someone trying to help some people then to ech his own.

What's you opinion of Tivo on the NEC 50 from up close, say 6-8'. My best layout configuration to put a unit on the wall requires one seat (mine!) to be around 7' from the display. I use DirecTivo as well but have recently become a SageTV convert which I feel is now comparable in quality to DirecTivo.

My dillema is this....I want to use HTPC as the sole input today, will need to sit rather close, and want to get 1-1 pixel mapping with square pixel. This leaves me with the choice of an 42" ED or a 50" HD to get 16:9 square pixels. If I'm going to bite the bullet I'ld like to get an HD TV but am I too close for a 50" (am I too close for 42" ED???). Seems like somethings gotta give but....

Gonna go to Tweeter again today and try to take a closer look up close to SD signals.

Thanks!

There square pixel thing comes into play with using the display for PC desktop and photographs.

If you can afford it go for the 50. I think the Panny 50 Commercial version with DVI blade is also worthy of consideration. Nobody comes close to their black levels.

For the record, I am very happly with my 61 and I sit 11' from the screen.

Heres a quote from my post on the UK avforums, thought it might be interesting reading here:

Quote:
My attention had been caught by the new NEC MX2 range of plasmas due to the large amount of praise they have been getting on the AVSforum and now some mention on this forum. I noticed that there was quite a bit of confussion regarding the information on the displays processing (8,10,12 Bit, greyscale and displayable colours) given by various websites (NEC USA, NEC UK, retailers..) and people on the forums.
I decided to send NEC an email requesting confirmation and told them that their websites were stating contradicting information, anyway this was the reply I got....

Quote:
Technical support NEC Europe
Dear Mr Scot,
The 42XM2 uses new 12 Bit sampling technology which enables the monitor to
process and sample 68.7 billion colours from video sources connected to
the monitor. This produces improved dark scene detail and reproduces subtle
colour shades within the picture which can only resolved using 12 Bit video
sampling.

Here he is reply to my comments questioning whether the UK website needs its specs updating

This specification is in respect of the processing with-in the monitor. The
display specification of 256 grey scale and 16.7 million colours is
correct.
Our us website should have been clear in stating the 68.7 billion colours
was the amount of colours which our screens can sample from Video, PC
graphics, High definition, and other professional broadcast video sources.

Regards,
Simeon
Don't know about the rest of you but this seems like quite a big thing, some people are going wild about this plasma stating how it has this huge greyscale (4096 compared to Panasonic, Pioneer and Fujitsu with 1024) and massive amount of colours (68.7 billion compared to Panasonic, Pioneer and Fujitsu with 1 billion) and this is giving a much better picture and no banding or solarisation and yet it turns out that unless they are using a source which already has 12 Bit video (don't know what this would be? Apart from computer produced material) then they are in fact using a display with the same processing capabilities as the other manufactures previous generation models??

This seems very strange, am I getting the wrong end of a stick somewhere along the way or what, is this actually how all the other manufactures displays work?

I was quite interested in the new NEC's as a possible replacement for my Panasonic if I'm unable to get a quiet one but this would put me right off...

rscott4563,

Thanks for the update. That information makes sense to me.
I am very happy with my 61XM2.

When runing low quality sources, I see more banding and posterization than with my Pioneer 503CMX.

It seems the distinction is "sample from" and "display". It may be able to accept a 12-bit input but it displays an 8 bit image. This kind of thing is common with video cards. It's like higher precision internal calculations that reduce rounding errors when the data is output. Still the way the responses are worded and the specifications are stated is confusing, perhaps purposefully so. Typical marketing doublespeak. I work in computer hardware marketing. In fact, I work in what is called "technical marketing" - more or less and oxymoron. In theory I try to make engineering geek talk understandable to our customers, but I can't claim the process and result is 100% honest.

I got my 42XM2/S last Friday, I am sill wiping the drool off my face, but it keeps coming back. Anyways, I was wondering if all other owners of this set notice the following:

When there is no signal on the component or s-video inputs for example, and you turn the set on, it goes from pitch black (power-off) to a grey cast (power-on). This grey cast establishes the black-level of this set and there is no advanced menu setting that can lower it. I've tried all, and only the PLE level (Long Life menu) seems to affect it in the opposite direction (makes it lighter grey).

This observation can only be seen at night, with low ambient light. Is this normal or do I have something wrong with my set? I am yet to try DVI and RGB (15-pin), will do on Friday when these cables are delivered to me. I am using an LG 3510A DTV/DVD and Dishnetwork SAT.

You are probably seeing the lowest level of black that the screen can produce. You can verify this by using the remote to bring up the menu. If the black background of the menu matches the screen, this is a black as it gets.

Correct, the menu background blends with the whole screen. However, this tells me that the plasma cells get Energized for no reason. I am inclined to think this will decay over time as the set loses brightness and approaches it half-life. But it is only wishful thinking and a darn long time to wait for perfect blacks :( Any insight on this subject would be appreciated.

PS. Gamma setting doesn't help, it only crushes the blacks so I keep it set to 1 to see the step from IRE 0 to IRE 10. I use AVIA.

While there can be residual glow after bright scenes, it fades quickly.

I think you have come upon the reason why there is so much discussion on the black-level's of plasmas. I have dimmable lighting so I keep the lights on a bit and most of the time it is not a problem.

It is unlikely that your screen will get appreciably better over time.

So I take it the grey cast (w/ no input signal) is not unique to my set? And that this is the normal dark state for my NEC 42XM2/S?

I cannot say for sure since I do not have that model. I have a 61xm2/S. But if the menu black = the rest of the screen. That is as good as it gets.

There are a lot of nice things about NEC plasma. Grayscale, color accuracy, brightness. They are stunning. Black are good, but only about 2x of a panny.

post #284 of 285
Agreed, even though the blacks are less than ideal after dark, it doesn't make me wanna send my 42XM2/S back. There far too many advantages AFAIAC that swing the balance in favour of keeping it. I am just double-checking to see if other 42XM2/S owners notice the screen going grey when they power the set up without a signal on any input.

I've been looking at RemoteCentral, specifically at this page

http://www.remotecentral.com/cgi-bin...smadisplay&fc=

, but can't seem to get the discreets for HD2 to work correctly. I found this page on NEC's website but don't know how to use the codes on the second page. Does anyone know how to convert these to dicreets (if even possible?)?

http://www.necvisualsystems.com/corp...XM2S_IGv10.pdf

Any tips from you guys would be great!
